DEEP-miseries GANG-PLOW.

Patented Nov. so, 1915.

" Application filed May 23, 1912. Serial No. 699,208.

To all whom it may concern:

Be it known that 1, PETER B. CRANE, of Long Lake, Hennepin county, Minnesota, haveinvented certain new and useful Improvements in Deep-Tilling Gang-Flows, of which the following'is a specification.

The object of my a deep tilling plow by means of which the soil can be thoroughly stirred and cut up to a considerable depth, the plows being arranged so that oneplow will travel in the furrow cut by the preceding plow.

A further object is to provide a gang plow in whichboth sets of plows will be movable vertically, independently of one another and be capable of riding over an obstruction in the ground without affecting the other plows.

Other objects of the invention will appear from the following detailed description.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming.

part of this specification, Figure l is a rear view of a deep tilling gang plow, embodying my invention Fig. 2 is a plan-view of the same, Fig. 3 is a detail sectional view showing the manner of mounting the plow beams on the frame of the machine.

In the drawing, 2 representsthe frame of the machine having forward carrying wheels 3 and 4 provided with lever mecha; nisms 5 for raising and lowering them and a rear caster wheel 6. The frame is, provided with extensions 7 and 8 at the ends thereof on which the wheels 4 and the caster wheel 6 are mounted. Between theseextensions a recess 9 is formed. 10 and 11 represent bars secured at their ends to the eX- tensions 7 and 8 and extending in parallel relation wlth one another over the recess 9.

12 and 13 represent forward and rear beams, pivotally supported on bolts 14 which are mounted at one end in the machine frame and supported at their other ends in I-bolts 15 having threaded ends projecting through flanges 16 a-nd provgided withadjusting nuts 17. By means of these I-bolts and adjusting nuts the bolts 14 may be tilted slightly to shift the beams laterally and change the position of the disks 18 and 19 mounted thereon. I

invention is to provide gle disk of one land, and the other ment of the levers will determine the mounted on the beams 12 and the rear group the disks 19 mounted on being composed of the beams 13. The beams and disks are so arranged that a disk 19 will follow in the furrow cut by adisk 18 except at the front and rear ends of the machine, where a singroup is'provided. At the I prefer to l forward end of the machine I prefer to provide one beam 13. and a disk 19, forming the forward disk of the rear group, and at the rear end of the machine I provide a single beam 12 and a disk 18 thereon, forming the rear disk of the forward group. The forward disk 19 on the second time around the land will travel in the furrow that was cut by the rear disk 18 on the first trip around the disks 19 of the rear group will follow in the furrows cut by the disks of the forward group and increase the depth of cut thereof. Upon the beams 12 and 13 I prefer to arrange suitableweights 20, which are adapted to force the disks into the soil tothe required cutting depth. These weights may be increased or decreased in number according to the desired" pressure of the disks.

For the purpose of limiting the depth of cut of the disks I provideiiexible means, such as chains 21, connecting the beams with independent, levers 22 and spectively on the bars 10 and 11, one set of levers operating to raise 'or lower one set of beams and the other set of levers for raising or lowering the other set of beams. Suitable quadrants 24 are provided in connection with the levers with which locking latches on the levers engage. By m ans of'this machine a series of furrows may be cut and as each disk operates'independently of all of the other disks itmay rise and fall as the machine moves along, riding over an obstruction and accommodating itself to the character of the soil without being affected by theposition of the other disks and the adjustdepth of cut of any one of the disks independently of all the other disks. The bars 25 dependvertically from the bar 11 in position to contact with the rear portions of the beams and hold them against lateral movement under 23 pivoted ref mounted in the frame of the machine and as the operating levers are located directly above the beams the person in charge of the machine has quick and accurate control of each beam and disk.

The plow disks in this application may be operated in substantially the same manner as shown and described in my pending applicatien on tilling machines, iled February 15, 1912, Serial. No. 677,736, inwhich a single pair of disks is shown, one pivotally supported and operating independently of the other. The machine of this. application involves a number of these disks, arranged in staggered relation to one another, and beginning at the forward end of the machine, the single disk shown may be utilized to out a deep furrow while the adjacent disk of the forward roav may cut a shallow furrow that is incr ased in depth by the disk immediately following of the rear row, and this operation may be carried on entirely across the machine, the rear disk of the forward row cutting a shallow furrow in which the forward disk of the rear row may run on the second time around the land, as hereinbefore stated.

I claim as my invention 1. A deep soil gang tilling machine comprising a frame having carrying wheels, a series of beams pivotally connected with said frame, said beams being arranged in rows obliquely with respect'to the line of travel, a series of disks mounted in groups on said beams, the disks of one group being in advance of those of the other group and offset with respect thereto, the rear disks traveling in the furrows made by the forward disks.
